Web1 Jun 2024 · Although chromatin bridges and lagging chromatin are always pathological (generating aneuploidy or complex genomic rearrangements), the main subject of this article, the ultrafine anaphase bridges, might, in addition to potentially driving genomic instability, play critical roles for the maintenance of chromosome structure in rapidly ... WebRif1 thus acts as a double-edged sword. Although it inhibits the resolution of taz1Δ telomere entanglements, it promotes the resolution of non-telomeric ultrafine anaphase bridges at ≤20°C. We suggest a unifying model for Rif1’s seemingly diverse roles in chromosome segregation in eukaryotes.
